Resetting consumables for OKI C7300,C7500,C9300 printer I think! 1. Hold buttons 0 + 1 + 6 + 7 on startup. 2. Press button 0 several times until "DIAGNOSTIC MODE xx.xx.xx" shows. 3. Hold buttons 2 + 3 until "ENGINE DIAG LEVEL 4" shows. 4. Press button 1 to scroll to "COUNTER SET". 5. Press button 2 to scroll through menu items (button 6 scrolls backwards) 6. To alter the value of an item, first press button 3 to select the digit to be altered. The selected digit will slowly flash. (Button 3 moves to the right through the digits. Button 7 takes you to the left.) 7. Then press button 2 to increase the value of the selected digit. Press button 6 to decrease the value. 8. When the changes have been made hold buttons 1 + 3 + 5. The screen will flash three times and then an * will appear on the right of the screen. The new value is set. 9. To leave the counter set menus, turn the printer off. IMPORTANT Each colour toner counter shows life as percentage used. So a toner showing 30% has used up 30% of its toner. 100% would indicate a near empty toner. This is the reverse of the toner life shown from the "usage menu" when the printer is in normal operation, which shows the toners as a percentage life remaining. You will want toner showing 00%. note:this is oposite of what you see in user mode Some models exhange these steps 3) HOLD 0 + 4 "ENGINE DIAG LEVEL 2" shows 4) Press 1 to cycle to "fuser unit" 5) 2 to scroll to TONER REST IS SAME WE WANT TO SET WHAT i GUESS IS AT 100% TO 0%.

Try cleaning the glass area where the copies are laid.

I sounds like a problem with your print head or possibbly a leaking one. Run the head cleaning a time or two to see if it clears up. Sometimes ink will leak into the machine and streak on the following pages until it wears off the internal part.

Feed rollers are the rubber tires in your printer that pick up paper. They spin in the direction of the paper movement. They wear out over time due to use, and will need to be replaced. Pads are usually used for seperation and can be a flat peice or a round roller. They sit under the pickup roller and stop more than one piece of paper from being fed.
